To all whom 'it may concern:

Be it known that I, GREENE HULING, a citizen of the United States, residing at Hampton, inthe county of Windham and State of Connecticut, have invented new and useful Improvements in LockingA Devices for Dump-Carts, of which the tollow ing is a specification.

This invention relates to locking devices for dump carts, the object of the same being to provide simple and eiiicient means whereby the cart body will be held securely in position for operation and in such a manner as to permit the ready release of the same for the purpose f dumping.

A further object- .of the invention' is to provide a locking device which may be readily applied to and used in connection with dump carts vof various constructions Whether adaptedl to be drawn by one or two horses.

With these and other ends in View which will readily appear as the nature of the invgention is better understood, the same consists in -the improved construction and novel arrangement and coiribinat-ion of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claim may be resorted to vwhen desired.

- In the drawings,-Figure 1 is a side elevation showing the invention applied in position for operation and showing as much of a dump cart as is necessary to enable the invention to be understood, the axle and a portion of the cart body being shown in section. Fig. 2 is a similar View showing the cartbody in the act of dumping. Fig. 3 is an end view of the device as seen in Fig. 1. Fig. 4C is a perspective view ot the parts constituting the inventiomas seen from the opposite side to that exhibited in Figs. l and 2.

. Corresponding parts inthe several figures are denoted by like characters of reference.

The improved locking device includes two principal members, namely, a hook member A and a lever member B. The hooli:l A; comprises plate 1, the lower extremity Vot Specication of Letters Patenti Application led October 24, 1911.

which is bent to form a shallow hook-shaped projection 2. Said base plate is apertured for the passage otfastening members, such as screws, whereby it may be secured upon the front end of o ne of the sills 4 of the dump cart, the body of which is hingedly connected with the axle 5 in the usual manner to permit the 'dumping of the contents ot the body. The lever member B, which is 'ulcrumed by means of a bolt 6 upon one ot'.

the cart ways 7 that extend forwardly from the axle, is provided with an upwardly eX- tending heel 8 having a terminal hook 9I i adapted to engage the hook 2, as clearly seen in Fig. l of the drawings. The lever B is provided on one of its side facesad jacent to the way on which it is pivoted with a laterally extending iiange 10 adapted to rest upon the upper 'face of said way or beam, when the hooks 9 and 2 are in engagement with each other, the object of the flange l() being to limit the movement of the handle portion 11 of the lever in a down ward direction; not only when the hook .portions 9 and 2 are in engagementl with each other, but more particularly when the. hook 2 is disengaged from the hook 9 as is the case when the cartbody is tilted to dis charge the contents thereof. lVhen this is done the handle portion of the lever will drop by gravity, but it will be intercepted by the flange 10 engaging the upper face of thebeam or way 7, thereby maintaining Ithe hook member 9 in position to be again engaged by the hook member 2. The upper face of the hook member 9 and the lower face of the hook member 2 are beveled, as

shown, and it followsv that when, after discharging the contents of the cart body, the

latter is restored to its initial iposition, the

hook member 2 will engage the upper tace ofthe hook member 9. thereby tilting the lever handle in an upward direction until the hook members 2 and 9 pass into engagement. with each other, the said hook members being retained in interlocking engagement by the weight of thehandle portion ot'. the lever.

.\s will be seen trom the foregoing description, taken in connection `with the drawing hereto annexed, the improved cart loclt is extremely simple in construction, and it mayY be very easily operated for the purpose of enabling the cart body to be tilted to discharge the contents thereof. As soon as the cart body is restored to its ULG initial position,l the liook members automatilcally engage each other,'thus locking the cart body in-postion for operation.

Having thus described the invention, what i is claimed as new, ist- I a dump cart, an axle having a forwardly extending beam, a Vcart body including a sill hingedly connected with the axle, and a locking device comprising a plate se cured upon the front end of the sill and hav-A ing at its lower extremity a lrearwardly extending hook mem-ber, and a lever pivoted -upon the beam and having an upwardly extending heel portion terminally hooked to engage the hook member of'the plate, said Y www,

lever having also a forwardly extending handle portion provided with a laterally projecting flange engaging the upper face of the beam upon which the lever is fulcrumed; the opposed faces of the hook niembers upon the lower end of the plate and on GREENE HULING.
